Quick Overview of Karcepts Rear Wheel Hubs | Honda S2000 

Glad you’re okay. That looked pretty harsh.

I’ve never seen an s2k flip! Thankfully you’re okay! Did you have a roll bar or was it the oem roll hoops?

@@kassiypomme7696 I don’t think that was an s2k

@@suryamp12 that definately wasn't an S2K

It was an MR2, but it did break a rear hub in the same way an s2000 could. It had a roll bar.

I think they last plenty long. I’ve done about 40 track events on OEM or eBay hubs

I don’t know how much I can review these beyond they broke or they didn’t. 😛

I dont think street driving will ever experience a rear hub failure like track abuse will.

Agree. Would not bother for street driving.

Ive brought a track s2000 but im daily driving it pretty hard, would you say past track abuse might of weakened them?

@@DIYGuysvideo thanks for replying. Seeing crashes like that just makes my heart drop and paranoid lol

Yes. Heavily on very sticky tires.

No

Yep

I just personally don’t understand the quenching and tempering process. The other points are pretty straightforward and understandable to someone like me.

@@DIYGuysvideo ah I see. its basically just that process of improving the hardness and ductility of the metal. Briefly explaining, you heat the metal at very high temperatures and then oil quench (cooling it down) quickly so the grain structure changes to improve on its hardness. The downside is, even though the metal becomes harder, it does become more brittle. And thats where tempering comes in afterwards. You heat the metal again but at a medium to high temperature and you let it slowly air cool afterwards. That process releases the stresses and brings back some of the ductility in sacrifice for some hardness.

Martensite :)

@@DIYGuysvideo its the final step in history channels forged in fire - its the part that makes or breaks any blade

I don’t know about structural rigidity but I’d say the hubs would take less heat and last longer for sure. Gary Wong who broke his rear hub was running the urge rears for probably over 50 track days though. Not sure how long he was on those hubs for though.

The rear hubs were about 2yrs old with about 50-60 day on them. Karcepts on now. 8 days so far. No issues 🤞

Heat is only one factor, but not the one that would mainly cause hub failure. The tire technology has advanced a ton since the OEM rear hubs were designed. These cars are taking much higher lateral forces that are putting unexpected stress on OE hubs. Karcepts hubs are designed to take more stress.

That wasn't an S. It was a different car, used to illustrate the potential chaos a broken hub can bring. Highlight seriousness of the topic.
